A form of 

 and IEEE 802.3 network cabling using 

provides 10Mbits/s with a maximum segment length of 100 m (382 ft).

An implementation of 

 Ethernet standard, often called thinnet 

or cheapernet, because it uses thin coaxial cable. 10BASE2 runs at a data 
transfer rate of 10 Mbits/s with a maximum segment length of 185 m 
(607 ft) per segment.

The emergency service that provides a single point of contact for police 
and fire departments. See also 

.

Codes that allow you to keep track of calls associated with a client or 
account for bookkeeping or billing purposes.

Asymmetrical Digital Subscriber Line. A telephone line that delivers 
high-speed data services, such as Internet access, videoconferencing, 
interactive TV, and video on demand. The line is split asymmetrically so 
that more bandwidth can be used from the telephone company to the 
customer (downstream) than from the customer to the telco (upstream).

Asynchronous Transfer Mode. A cell-based data transfer technique in 
which channel demand determines packet allocation. ATM offers fast 
packet technology, real-time, demand-led switching for efficient use of 
network resources.

The Attendant Console is a standard telephony device that shows the 
status of each extension in a telephone system. The Attendant Console is 
usually used by a receptionist to connect incoming calls to the correct 
extension. All incoming calls ring at the Attendant Console.

Attachment Unit Interface. The IEEE 802.3-specified cable and connector 
used to attach single-channel and multiple-channel equipment to an 
Ethernet transceiver. Defined in Section 7 of the 802.3 standard.
